All the BCC disciples that I met glowed with friendliness, enthusiasm, and idealism. Ryan mentions the integrated Johannesburg Church of Christ; I suspect that the BCC itself is one of Boston's most racially diverse congregations. I heard no claims of financial fraud or physical violence against disciples or ex-disciples. My impression is that everyone up to the top of the organization believes in what they are doing.
However, whenever I heard disciples talk to one another, they used the noun "Christian" to mean "a member of the BCC, or of one of its affiliates." All the ex-disciples that I talked to agreed that these were not isolated incidents, but examples of the BCC's doctrine.
Perhaps the ICC's members would claim that their church has reformed over the past four years, and that critiques of their practices are based on out-of-date information. I wouldn't trust such a claim, since Al Baird, the leader of the BCC, said the same thing back in 1989, and it wasn't true then.
